The ‘Matthew Boulton Coin’

A commemorative Matthew Boulton Coin has been produced by A.J. Gilbert (B’ham) Ltd of Buckingham Street. Tel: 0121 236 7774.

The coin is produced from 99% pure copper which is cut into strips ready to go through the blanking tool which produces the plain 40mm diam. coin blanks. The blanks are then put through a burnishing barrel to be thoroughly cleaned.

The coin blank is then place into a collar and the dies have to be cut with the Matthew Boulton/Britannia design designs close together within the collar when the press is operated under an approximate pressure of 180 tons.

The strike is repeated twice and the coin is automatically ejected from the collar.

This particular coin, which is based on the Cartwheel Penny has been left in natural copper as was the original.

The dies and collar used for the production of a coin such as this are of the highest quality and in the case of the Matthew Boulton coin would cost £1500 for the pair.
